P6 Key Terms
Pink- Higher and Foundation Tier
Blue- Foundation Tier
AND gate- Logic gate whose output is high when both inputs are high
Base- One of the terminals of a transistor
Battery- Scientific name for two or more cells connected together
Bridge circuit- Full-wave rectifier made from four diodes
Capacitor- component that stores charge, usually on a pair of parallel plates separated by an insulator
Cell- A device that transfers chemical energy into electrical energy
Collector- One of the terminals of a transistor
Diode- Component that only allows charge to flow through it in one direction
Dynamo effect- Where changes of magnetic field around conductors result in the generation of electricity
Electric motor- Device with a rotating shaft powered by electric current interacting with a magnet
Emitter- One of the terminals of a transistor
Fleming’s left-hand rule- Uses thumb and first two fingers of left hand to show directions of force, current and magnetic field in a motor
Full-wave rectification- Process of using both positive and negative parts of alternating current to make direct current
Generator- Machine that rotates to generate electricity
Half-wave rectification- process of allowing only the positive parts of alternating current to pass through
Iron core- Central part of a transformer around which the primary and secondary coils are wrapped
Isolating transformer- Transformer with the same number of turns on the primary and secondary coils
Light-dependent resistor- Special type of resistor whose resistance decreases when the intensity of light falling on it increases
Light-emitting diode- Diode that emits light when an electric current flows through it
Logic gate-Circuit that has two levels…
